Lightroom: Deleting images using arrow keys

When deleting images in Lightroom I would prefer to use the arrow key, instead of the mouse, but this is not possible because the last action 'permanently delete files' demands me to mouseclick rather than use the arrow key to permanent delete images.The procedure is today: press 'DEL' > arrow key left: 'delete from disk' > mouse click: 'permanently delete files'.It should/could be: press 'DEL' > arrow key left: 'delete from disk' > arrow key right: 'permanently delete files'.I don't see any risk of deleting any images by accident, but it will make it a lot faster to delete images.

You could bring back some mouse actions to reject the images first and later on deleting them in a batch.Reject is done with the X key. With auto advance you go to the next image automaticaly. At the end of the culling you can go to the menu and delete all rejected images.﻿

Roelof's solution is the fastest way to accomplish your task and is the way most people do efficient culling of unwanted pics with the fewest keystrokes and mouse clicks.

On both Windows and Mac, you can use the tab key to move the focus to the Permanently Delete Files button. On Mac, you'll have to set the option System Preferences > Keyboard > Shortcuts > Keyboard > All Controls (at the bottom of the window).
